Thank you all for your answers.

I would be careful with putting a tank in a hallway, especially if you have timber floors i.e not a slab concrete floor, since many timber floors have give in them and with frequent walking up and down the hallway the tank may get some undesired movement causing the tank/ stand to sway. Also in a hallway because its generally transient, as in your usually moving past not lingering, the fish may end up being more skittish every time somebody does move past the tank. Ideally I would always put a fish tank where you can comfortably sit and enjoy watching them, while they in turn watch you.
I cant really help you with your selection of cichlids, since my limited experience with them in general has been " does not play well with others" . But I do know if setting up a rift valley type cichlid tank then your best bet is to get all males. This way they show the best colour, and there is no chance of accidental cross breeding also it reduces the chances of breeding aggression.
As for your compatible tank I would increase the otocinclus to as far as room and budget will allow. Otocinclus are social fish and need plenty of company of their own kind. I would not introduce oto's to a newly established tank, they eat diatoms and biofilm rather than algae and there is not plenty of the right food source in a new tank to support otocinclus.
Mollies do better in slightly hard to salty water, but I have seen them living just fine in pure fresh water.
Platties too tend to do better in hard water, although I kept some for years in pure fresh water, just keep in mind with platties and mollies (and guppies) they are usually kept in shops etc with salt tonics to make the water hard, this same water is not suitable for soft water species such as gourami and tetra. By leaving out the mollies and platties you can increase your tetra shoal size which will make the tetras happier and behave more naturally.
Even though tetras and gouramis are from different sides of the world they at least have similar water requirements and will work well with otocinclus. Other fish that also work well with gourami and tetra are almost any of the corydoras species ( usually found along side tetras naturally in the wild) and khuli loaches which are found in the same general countries as gourami.
Depending on what type of gourami you get will really depend on the ghost shrimp surviving. Shrimp are naturally on a gouramis food list. I find shrimp relatively easy to keep, but watch out when purchasing them because many places will call any clear looking shrimp ghost shrimp. Many a person has unwittingly purchased macrobachium shrimp and found out the hard way macrobachiums are not generally any good to have with fish. Because of your desire to also have shrimp I would also have live plants in the tank, as most shrimp spend almost all their time hunting through plant life for food tidbits. Other shrimp you may be interested in are Cherry shrimp (many colours to choose from now, just don't mix the colours), Bamboo shrimp (but these are filter feeders and are fairly specialised), Amano shrimp, even pinocho or rednosed shrimp.
Since i'll (most) likely be moving into the same complex I live now (just different unit), the floors are tiled and on ground level. I'll take into consideration of the fish being jumpy, would it help if I put lots of hiding/exploring places for them? Or is it just the constant movement that would freak them out?
I've had otos before and I love them so much. They're such funny little guys, and mine were pretty hardy. I loved watching them hang out with what seemed like their "friends" and just follow each other around the tank. I've only really had 4 at a time, I can increase the number to 6 though if it would make them happier.
I've also had red wags before in a tank with guppies so they mixed well, but i'll take them out since it's a different water type. The only problem with that is I like a lot of colour and species diversity, so i'm trying to make that work while still hopefully sticking to whats best for the fish and matching types (which is why I asked advice from you guys).
As for the shrimp I was thinking of getting one of the bigger gourami's as a nice change, but if that'll make it more likely for it to eat the shrimp then perhaps i'll get a dwarf again instead. I used to have a powder blue named Blue and he had a great personality, he would feel the bag of any new fish with his feelers and spit water at my hand when I went to feed them. I wouldn't mind having something like that again, although I know you can only have one male in a tank if I remember correctly.
And I was definitely planning on having a live plant tank. I love the look of them, and it's the best for the fish as well so it's a win-win.

Hello Blue,
before chosing fish it would be good to know your water parameters. What is your temporary and permanent hardness? Are you willing to change them by using reverse osmosis?
So I will only comment on your cichlid choice: Mixing different locations is not a good thing as requirements differ. Also from my personal experience those different cichlids "don't play well together" (lovely describtion @Baccus) as there communication is slightly different. It is better to stick to one location only and strictly. Which also means not mixing fish from different African Great Lakes (different water). Moreover 75g is at the lower end for any Great Lake setup and is defnitely too small for Green Terrors, except you want to keep a single fish only.
I'll be honest, i'm not the best with water. I usually get a good filter, heater, and then let it do it's own thing. As for the cichlids, I suppose i'll have to look more into where each one comes from. I heard they don't mix well and I thought i'd looked and made sure they all came from the same area but I think instead I may have just separated old/new cichlids. I think I looked up the size they got too and calculated it, I used the inch per gallon rule, I think.
And I did say 75 or bigger, though there is still a possibility it could only be 75 but i'm hoping for larger.

I second that you should not mix cichlids like this. The jewel should be kept alone. The water requirements would not work. Some of the fish need hard water and some need soft. Are you on the ground floor? 75 gallons of water will weigh in at 600 pounds or 272 kilograms. Plus filter, substrate, lighting, etc. It will get heavy fast.
The second list should fit in a 35 gallon tank. I would start with a single tank and get that established before getting the second larger tank. I have a 55 gallon, two 29 gallons, a 10 gallon and a 6 gallon tank. I spend a good 10 hours a week in maintenance alone. Maybe more.
The living rooms (where I would keep the cichlid tank) are on ground floor as well yes. I wouldn't put that large of a tank on a higher floor.
I would probably end up starting with the smaller tank and getting the cichlid one later on, mostly because I'm more familiar with common freshwater fish and (obviously) not that educated with cichlids. I'd want to learn a lot more before purchasing anything.
